City of St. Joseph Water Protection Division Fats, Oil, & Grease Program Information

Fats, oil, and grease (FOG) is a common problem for wastewater utilities nationwide and is most frequently a result of waste product from food preparation and dish cleaning at Food Service Establishments (FSE). FSE are major contributors to blockages in the city’s collection system. One of the most effective measures of FOG control involves the installation and maintenance of grease removal devices. This source of pollution is also easily preventable by good kitchen management practices and proper maintenance of the grease removal device. In order to protect human health, water quality, and the beauty of St. Joseph, all FSE must do their part. These are some frequently asked questions about the FOG Program.
